Be it known that '-I, SAM-om. 0. Film!- MENT, a citizen of the United States, and a resident of Lockport," in the county of Will and State of Illinois, have invented certainnewjand useful Improvements in-Concre'te- Construction'; and-I do hereby declarethat the following-description of my said'inven tion, taken in connection with the' accom panying sheet of drawings,- clear, and exact specification, enable others skilled in the-.arts. to which 1t apl ertains to make and use-the same.

T s invention has general reference. to improvements in concrete construction; and its object is to make buildings constructed of concrete, water, and damp-proof.

-To attain thisobject, my invention consists in the novel and peculiar combination of parts-anddetailsof construction as hereinafter first fullyfset' forth and described,

and then pointed outin the claims.
